PVCCS2 - Model polynomial voltage-controlled current source with two controlling inputs

Library

SPICE-Compatible Components/Sources

Description

The PVCCS2 (Two-Input Polynomial Voltage-Controlled Current Source) block represents a current source whose output current value is a polynomial function of the voltages across the pairs of controlling input ports. The following equations describes the current through the source as a function of time:

where:

• V_in1 is the voltage across the first pair of input ports.

• V_in2 is the voltage across the second pair of input ports.

• p is the Polynomial coefficients parameter value.

The block uses a small conductance internally to prevent numerical simulation issues. The conductance connects the output ports of the device and has a conductance GMIN:

• By default, GMIN matches the Minimum conductance GMIN parameter of the SPICE Environment Parameters block, whose default value is 1e–12.

• To change GMIN, add a SPICE Environment Parameters block to your model and set the Minimum conductance GMIN parameter to the desired value.
